BUILDING CONSTRUCTION.

Original application 'filed February 25, 1928, Serial No. 90,447.vDivided and this application filed November 17, 1927.

This invention relatesto building construction, and particularly tobuildings having a structural metal frame. and a metal sheathing, andaims to providea building of this character which may be easily. andeconomically erected. A

Inniy co-pending application filed February 25th, 1926, Serial No.90,447, I have described and claimed a standard construction which maybe applied in a uniform manner on any flat wall or roof surface of sucha building. The present application, which is a division of theaforesald application, relates particularly to a construction to be usedat the corners of such building.

In order that the invention may clearly be understood, I will describein detail the specific embodiment of it shown in the accompanying'drawing which is a fragmentary horizontal-section of a corner of thebuilding.

The frame of the building illustrated is of usual constructionconsisting of cornerposts, one of which 10 'is shown in the drawin.which serve to support horizontal si e beams 13. v a

The frame is covered with a metal sheathing of rectangular galvanizedmetal sheets, two of which, 0, 0",.are shown in section in the drawing.

The sheets 0,0" are hung on the side beams 13 by means of hook flanges21, 21 and may also be bolted orfotherwise secured to the side beams bymeans not shown in the drawing. In placing the sheets 0, c on the frame,a

space is left between the side edges of the sheets atthe corner of thebuilding. To provide for applying and retaining a cover-piece.

to cover this space, the side ed of each sheet at the corner of thebuilding 13 provided with a retaining flange 26' havin the form of anangle flange spaced inwardl from the side edge of the sheet and inclineat 45 to the sheet and with a cam flange 2:? extending from the edge ofthe le flange. -The retaining flanges and. cam anges of each sheet areintegral with the sheet and are formed by Serial No 233 751.

bending the side edge portion of the sheet, first back on itself at theouter side of the sheet, then outwardly at an angle of 45 to -spacebetween the edgesof the sheet a, c'at the corner of the building to makea water- 5 tight joint. The cover-piece 40 is made of sheet metal andhas the form of a channel with its sides 41, 41 flaring outwardly fromits top. At the lower edges'of the sides 451,41 of the cover-piece areengaging elements 43, 43' having the form of inturned angle flanges.

After the sheets have been placed in position, the cover-piece issnapped over the angle flanges of the sheets. This is done in the following manner. The 'coveriece 40 is first placed with one of its angleliitnges' 43 under the angle flange 26 of one of the sheets. This bringsthe lower edge of the other angle flange 43 of the cover-piece over theupper edge of the cam flange 27 of the other .sheet. The cover-piece isthen presseddown, and, as it is made of resilient sheet material, itslower edges spread apart as it is pressed against the cam flange so thatits angle flange passes over the cam flange and snaps in against theangle flange 26 of the sheet. The coveriece is then held firmly in theposition in whlch it is shown in the drawing.

What is claimed is: V

In building construction, two sheets located on adjacent walls at acorner of a building,

- inturned retaining flanges at the side edges of said sheets at thecorner of the building, a cam flange extending from the outer ed e ofeach retaining flange in a direction para llel to the sheet on which theretaining flange is formed,
